Used as a SPI master, this Xpress series device lets you play the role of a bus master from the host PC.
As a SPI analyzer, it lets you sample the serial protocol traffic for checking and analysis.
- 50 MHz max SCLK frequency
- 25 MHz max sampling frequency in analyzer mode
- Up to 5 slaves
- Zero-latency between accesses
- Support of all modes (data toggle edge / data sampling edge selection)
SPI Xpress can be used against standard Serial Peripheral Interface protocol ports as a master and analyzer. It also supports:
- basic 3-wires protocols that use a single bi-directional data line and a predefined sequence. This sequence is composed of 3 phases: Write - Bus Turnaround - Read. For more details and for choosing alternative adapter solution, please see 'Which serial protocol do you use ?' in our selection guide.
- simple variations of SPI protocol based on signal polarities.
As a palm-sized, PC-based and USB-powered SPI host adapter tool, it typically suits embedded system development and validations usage scenarios, when there is a need to test and debug at signal level by interacting with each component of a serially-interconnected system.
- Stop quitting your desk for trials in the lab
- Stop waiting for the bench-top logic analyzer or signal generator to be available
- Place your debug tool next to your laptop on any desk
- Perform manual bench testing on your digital system (board, FPGA, ASIC, SoC) prototype
